SPECIFICATION forming part of Letters Patent No. 359,610, dated March 22, 18 87.

Application filed November 19, 1886. Serial No. 219,345. (No model.)

To aZZ whom it may concern.-

Be it known that I, ELIAS JEWELL, a citizen of the United States, residing at Wheaton, in the county of Du Page and State of Illinois, have invented certain new and useful Improvementsin Combined Railway-Chair and Nut-Lock, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part hereof, and in which-- f Figure 1 is an end elevation of my improved device with rail. Fig. 2 is a longitudinal side elevation. Fig. 3 is an end View of chair,

showing lock e. i

struct my device as follows, namely:

Like letters refer to like parts. The object of my invention istocon'struct railway-chair in which the ends of the rails are held more securely than in the structures heretofore'in use for such purposes,and which combines with the advantages of a chair a nut-lock without involving any additional cost in making. To'attain said ends I con- 7 A plate of iron or steel is rolled into the form as shown in end elevation at b in Fig. 1, fitting under the rail a and around the outer edge of the base thereof, and its upper parts over the'top of the base of the rail and against the sides of the web, and its open ends against the under side of the head of the rail when it is locked in place, and when in its normal position the upper sides of the chair, from the outer edge of the base spring upward and out ,ward, as shown in the dotted outlines, facilitating thereby the introduction of the ends of the-rails I Upon either one or upon both sides of the chair, on the vertical sides 1;, are formed small projections e near the bolt-holes. Said parts stantially as specified.

are here shown curved and wider at the endf 4o than at the other end, 9, and they begin to rise from the side is at' f into an inclined plane having its highest part and end at y, where it forms a shoulder, which will be within the corner of the nut, as shown at h, whereby the nutis held from turning backward. Said projections are here shown curved and wider at the endf than at the other end, g; but the outline may be of any shape, so long as the projection forms an inclined plane with a shoulder, g,whioh shoulder will lie within the corner of the nut. WVhen such projections are placed on both the sides k, one of them will preventthebolt-headfromturning. Thesides 7c are made convex, so as to be yielding under the pressure of the bolt, which, together with the tendency of sides is to spring apart, forms an elastic bearing for the nut cl,so that it will always be securely held by the lock. The said projections 6 may be formed on the outer surface of the sides I. in the rollingniill; or they may be formed by meansof dies or punches and under the base of the'rail, and cone spondingly to the corresponding part of the railhead on the opposite side, formed in one piece, and whereof the parts above the base are elastic and provided with inclined planes, having a shoulder, g, to form a nut-lock, sub- Witnesses:
